the horizontal distance ( x direction) from A to C is 7 units and
the vertical distance ( y direction) is 5 units
Applying Pythagoras' Theorem to the right triangle
AC² = 7² + 5² = 49 + 25 = 74, hence
AC = 
= 8.6 units ( to 1 dec. place )
Answer: BCD
Step-by-step explanation:
A is incorrect since there is no angle Y to exist
Hope this helps
5. You can multiply 10 over 3 by the reciprocal of 2 over 3 to divide fractions. You get 30 over 6, and that simplifies to 5.
Use identity -
(a+b)² = a²+b²+2ab
(5+√3)² = 5²+(√3)² + 2(5)(√3)
= 25 + 3 + 10√3
= 28 + 10√3
= 2(14+ 5√3)
